The Los Angeles Fire Department also sent 50 firefighters including one helicopter to battle the blaze.

The evacuation order had applied to residents on Country Club Drive above Sunset Canyon, according to Burbank police. Officers were going door to door as the fire burned in Burbank hills, the agency said.

People hiking in the area of Wildwood Canyon and Stough Canyon Nature Center "must leave immediately," the Police Department initially tweeted.
